The localised application of microgranules in beet crops is a well-known technique to control nematodes among other nuisances. For an efficient treatment, it is needed that products should be distributed precisely and homogeneously. Until 1990, the "Station de Genie rural" studied regularity of transversal distribution of microgranule applicators fixed on spacing drills. Three hundred tests have been carried out on machines used on farms or by agricultural work concerns. Application accuracy depends on product features as well as distribution system, its adjustment and its wear. For some machines, the deviation between rows can be higher than the standard dose by 20 per cent. Consequently, flow control is necessary to guarantee correct spreading. If it is possible, it is often preferable to adjust each microgranule distributor independently instead of choosing the same adjustment for all applicators.
